The Clock Tower Resort's CoCo Key water park will remain closed until March 1 for maintenance, according to its web site.The Register Star reported in mid-January that the Clock Tower had lost its Best Western affiliation and the resort's management was undertaking a series of repairs and upgrades for the nearly 50-year-old property.That included shutting down the only indoor water park in Boone, Ogle, Stephenson and Winnebago counties during the crucial winter months for much needed maintenance and repairs.The original plan called for the water park to be closed from Jan. 6 to at least Feb. 7. But the CoCo Key website (www.cocokeyrockford.com) says the water park will remain closed until March 1.We have an email into management of the 250-room resort to ask about the repairs.
